[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] refer to Figure 1 and Figure 4 As shown, the utility model provides a rice insecticide spraying device, comprising: a water tank 2 with a shoulder strap 3 in front, a spraying mechanism for spraying medicine provided on the rear side of the water tank 2, the spraying mechanism comprising a crossbeam 11 and a plurality of nozzles 12 equidistantly mounted on the crossbeam 11, and a connecting pipe 13 connected to the bottom of the water tank 2 is provided between the plurality of nozzles 12.

[0029] Combine Figure 1 As shown, a support member is longitudinally provided on the rear side of the water tank 2 for support, a rotatable cross bar 5 is provided on the top of the support member, a cross beam 11 is provided at one end of the cross bar 5, and a direction rod 4 connected to one end of the cross bar 5 is provided on the front side of the water tank 2.

[0030] As mentioned above, when using the water tank 2, shoulder strap 3, and spraying mechanism provided by the utility model, the water tank 2 is the existing technology. The utility model does not involve the core components in the water tank 2, so it is not repeated here. The cross bar 5 is suspended above the water tank 2 through a support. When the water tank 2 is worn on the body through the shoulder strap 3, the cross bar 5 will not interfere with the worker. The direction rod 4 can drive the cross bar 5 to rotate on the top of the support, so that the spraying direction of multiple nozzles 12 can be adjusted. The liquid medicine in the water tank 2 is sprayed on the rear side of the water tank 2 through the connecting pipe 13 and multiple nozzles 12.

[0031] In this utility model, combined with Figure 1-2 As shown, in this embodiment, an adjustment mechanism for angle adjustment is provided between the cross beam 11 and the cross bar 5 , and a control mechanism electrically connected to the adjustment mechanism is provided on the direction bar 4 .

[0032] Combine Figure 1-2 As shown, the adjustment mechanism includes a connecting rod 10 and an electric push rod 9. One end of the connecting rod 10 is welded to the middle of the crossbeam 11, and the other end of the connecting rod 10 is rotatably mounted on the cross bar 5. The two ends of the electric push rod 9 are respectively rotatably mounted on the connecting rod 10 and the cross bar 5.

[0033] As described above, when using the adjustment mechanism provided by the present invention, the stroke of the electric push rod 9 can be adjusted through the control mechanism, thereby driving the crossbeam 11 to swing up and down at one end of the crossbeam 5 through the connecting rod 10, and then the angle of the nozzle 12 spraying the liquid can be adjusted.

[0034] Further, in order to facilitate the drive control of the electric push rod 9, refer to Figure 7 As shown, the control mechanism includes a power supply mechanism and a switch 21. The switch 21 is installed at the end of the direction rod 4. A battery compartment 22 for accommodating the power supply mechanism is opened in the direction rod 4. The power supply mechanism includes a rechargeable battery 23 and a plug 24. The rechargeable battery 23 is installed in the battery compartment 22. The plug 24 is detachably installed at the end of the battery compartment 22. The rechargeable battery 23 can be removed through the plug 24, thereby facilitating the replacement or charging of the rechargeable battery 23. The rechargeable battery 23 supplies power to the electric push rod 9, and the stroke of the electric push rod 9 can be controlled by the switch 21.

[0035] In this utility model, combined with Figure 1-3 and Figure 5-6 As shown, the support member of this embodiment includes a support rod 7 and a fixed rod 14. The fixed rod 14 is longitudinally installed on the rear side of the water tank 2. The top of the support rod 7 is provided with a bearing body 17 for rotation, and the bottom of the cross bar 5 is provided with a mounting hole 16 for accommodating the bearing body 17. The rear side between the support rod 7 and the fixed rod 14 is provided with a hinge 8 for folding and storing, and a locking mechanism for unfolding and locking is provided between the support rod 7 and the fixed rod 14.

[0036] Combine Figure 6 As shown, the locking mechanism includes a latch 15 and a shift block 6 welded to the side of the latch 15. A lifting hole 18 is provided at the top of the fixed rod 14 to accommodate the lifting of the latch 15. An opening 20 is provided on the outer wall of the fixed rod 14 to communicate with the lifting hole 18. The shift block 6 is movably installed in the opening 20. A locking hole 25 is provided at the bottom end of the support rod 7. When one end of the latch 15 is inserted into the locking hole 25, the support rod 7 is restricted from being folded and stored on the fixed rod 14.

[0037] As mentioned above, when using the support member provided by the present invention, the fixing rod 14 in the support member provides an installation position for the support rod 7 on the water tank 2, and the support rod 7 is hinged to the fixing rod 14 by the hinge 8, so that the support rod 7 can be flipped on the fixing rod 14, so that the support rod 7 can be folded and stored on one side of the fixing rod 14, and then the horizontal cross bar 5 can be stored in a vertical position, which is convenient for storing the equipment. When the support rod 7 stands on the top of the fixing rod 14, the shift block 6 is moved in the opening 20, so that one end of the pin 15 is inserted into the locking hole 25, and then the support rod 7 is locked on the fixing rod 14. At this time, the vertical cross bar 5 is unfolded into a horizontal position, which is convenient for distributing multiple nozzles 12 on the rear side of the water tank 2.

[0038] Further, in order to prevent the latch 15 from being disengaged from the locking hole 25, refer to Figure 6 As shown, a spring 19 is further provided in the lifting hole 18, one end of the spring 19 abutting against the latch 15. When the latch 15 is inserted into the locking hole 25, the spring 19 is in a stressed state, and the elastic force of the spring 19 prevents the latch 15 from being disengaged from the locking hole 25, thereby preventing the support rod 7 from being folded and stored on the fixing rod 14 without external force.

[0039] Furthermore, when the device is stored, the nozzle 12 is prevented from contacting the ground. Figure 2 and Figure 5 As shown, support plates 1 are provided on both sides of the bottom of the water tank 2 for support. When the multiple nozzles 12 are stored, they are all located above the bottom of the support plates 1. When the support rods 7 are folded and stored on the fixing rods 14, the support plates 1 provide support for the water tank 2 on the ground. At this time, the multiple nozzles 12 are all above the ground, preventing the nozzles 12 from touching the ground.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
